NSD: Not significantly different (P > 0.05). JM = juvenile male, JF = juvenile female, AM = adult male, PF = pregnant female, LF = lactating female.
aResults of linear regression using time as the independent variable for analyte data (dependent variable, across all years and animal groups) calculated separately for each location.
bSignificance (P ≤ 0.05) determined by location (TZ vs. PL) specific marginal mean (controlled for variance due to group and season) post hoc sidak comparison of the respective biochemical analytes.
cSignificance (P ≤ 0.05) determined for season (W = winter, S = spring, Sm = summer, F = fall) specific marginal mean (controlled for variance due to group and location) post hoc sidak comparison of the respective biochemical analytes. Only significantly different seasons are shown.
